sncfrroivAL GUN. A

Application filed March 2, 1916. Serial No. 81,732.

To all whom t may concern Be it known that I, EUGNE SCHNEIDER, a citizen of the Republic of France, residing at Le Creusot7 France, have invented a new and useful Improvement in Sectional Guns, which is fully set forth in the following specification.

This invention has for its object to provide an improved light sectional gun capable of being readily taken to pieces and transported, so that it can be quickly set up near a trench and be taken to pieces for transport by hand by troops in an attack.

The invention will now be more particularly described with reference to the accompanying drawings in which Figures 1, 2 and 3 are respectively a side elevation, a rear end elevation, and a plan of one constructional example of the improved gun. Fig. 4 is a side elevation partly in section on a larger scale, illustrating details. Figs. 5 and 6 are horizontal sections on the lines V-V and VI-VI respectively of Fig. 4. Fig. 7 is a partial side elevation viewed from the right hand of Fig. 6, illustrating details of the lower portion of the pivotsupporting base. Figs. 8, 9 and 10 are views drawn to a larger scale illustrating the means for assembling the elements (pivot and trunnion caps) forming the upper gun mounting. Fig. 8 is a side elevation partly in section on the line VIII-VIII of Fig. 10, and Figs. 9 and 10 are sections on the lines IX-IX and X-X respectively of Fig. 8. Figs. 11 and 12 are respectively a side elevation and a cross section through the axis of the trunnions of the gun, illustratingl the details of the meansY for attaching the removable shoulder piece. Figs. 13 and 14 are respectively a side elevation and a plan of a modified construction of the lower mounting.

The lower mounting of the improved sectional gun comprises a base A which sup` ports the pivot and which is adapted to be assembled by interengagement in a base plate B which is fixed to a rear platform C that serves for carrying the anchoring spades.

The lower mounting is more particularly characterized by the feature that the base A is provided with a series of removable frames D, preferably a forward frame and two side frames7 which serve in their operative position as supports for sandbags E (as shown in Figs. 1 to 5), or as abutments for the insertion of suitable anchoring devices such as pegs F (as shown in Figs. 18 and 14).

In the'example shown in Figs. 1 to 7 the interengagement between the base A and the base plate B is effected by means of a bayonet joint as shown in Figs. 4 to 7. For this purpose, the base plate B is formed with a. series of nibs Z2 designed to engage in notches a in the base A in assembling together the parts A and B. The assembling is eifected by turning the base A through degrees relatively to the base plate B, whereby a ramp al on the edge of the base A is caused to jam against the underside of the corresponding` nib Z) (Figs. 4 and 5) an abut against the end b1 of this nib.

The sandbag supports D are provided on their assembling edge with a transverse hinge pin Z so formed as to enter and become engaged in the hinge straps A1 on the base A.

For transport, the lower mounting is thus capable of being very quickly disassembled into a number of its component parts, namely, the base plate B with its spade platform C; the pivot-carrying base A; and the several sandbag supports D.

The gun barrel Gr is journaled for instance by means of hollow trunnions g formed on a trunnion hoop G1 (Fig. 12) in a small mounting which can be disassembled into its usual component parts, namely a pivot H that is fixed to the base A by means of pins h, and two trunnion caps I.

The pivot H and the trunnion caps I can be rapidly assembled together according to this invention, by the following means The trunnion caps I (Fig. 8) which are hinged to the pivot H in the usual manner, by means of pins i, carry each at its free end, a hook I1 engaging in a socket H1 in the pivot so as to form an eye for the reception of the plug of a bolt of peculiar construction working in a suitable recess in the pivot H. As shown in Figs. 9 and 10, this bolt comprises a plug J slidable in a recess 71,1 in the pivot and fixed by means o f a cross piece j to a spring stud K which is slidable in a recess 77,2 and is acted upon by a spring 7c. Normally, the stud is in the position shown in Figs. 9 and 10, the plug J having its full portion facing the socket H1. To engage the hooks I1 of the trunnion caps in the sockets H1, the studs have to be pushed inward, compressing the springs lo, so as to bring the notches J1 of the plugs J facing the said sockets. Then the noses of the hooks I1 can pass through the notches J1 and enter the sockets H3L as indicated in Fig. 8. The trunnion caps are then locked in position by the circumstance that the springs 7c return the studs into the position shown in Figs. 9 and 10.

As shown more particularly in Fig. 4;, the trunnion caps I are provided with hooks I2 for engagement with the holding devices L of a shield M which has its bottom edge engaged by a retaining ledge H2 formed on the pivot H.

The gunk comprises further a removable shoulder piece shown in detail in Figs. 11 and 12. The arm N of the shoulder piece is formed for this purpose with a tenon n having two nibs nl. By moving the arm N into position at right angles to the axis of the gun barrel in front of two notches in one of the hollow trunnions g, the nibs nl are able to enter these notches, and by moving the arm N into position parallel to the said axis the nibs nl will come behind two retaining shoulders g1. The attachment of the shoulder piece to the gun is then completed automatically by means of an engaging device, for instance such as that shown in Fig. 11, consisting of a spring bolt O which is mounted in the arm N and engages with its nose in a socket P in the gun barrel.

In the modification shown in Figs. 13 and 141-, the lower mounting comprises in addition to the base A, only a base plate B to which are fixed a forward and a rear platform Q provided with a suitable number of sockets for small anchoring spades F.

Vhat I claim is :h

1. In a light sectional gun, more particularly for trench use, the combination With the vertical pivot of the gun, of a lower gun mounting comprising a base for receiving said pivot, a base plate, means for detachably connecting said base to said base plate, a spade platform fixed t said base plate, and frames detachably connected to said base plate, serving in their approximately horizontal position as supports for sandbags, and as holders for spades or the like.

2. In a light sectional gun, more particularly for trench use, the combination with the vertical gun pivot, and each trunnion cap of the gun, and a hinge pin for hinging each said cap to said pivot, of a notched spring bolt for detachably fastening the free end of each said cap to said pivot.

In a light sectional gun, more particularly for trench use, the combination with the vertical pivot and the trunnion caps of the gun, of a shield, a hook on each of said trunnion caps, holding devices on said shield adapted to be engaged by the hooks on said trunnion caps, and a retaining ledge on the gun pivot, adapted to be engaged by the lower edge of the shield.

4. In a light sectional gun, more particularly for trench use, the combination of a removable shoulder piece, a bayonet joint for attaching said shoulder piece to one of the trunnions of the gun, and an automatic engaging device comprising a spring bolt between the arm of said shoulder piece and the gun barrel.

5. In a light sectional gun, the combination with the vertical pivot of the gun, of a lower gun mounting comprising a base for receiving said pivot, a base-plate, means for detachably connecting said base to said baseplate, and anchoring frames detachably connected to said base-plate.

6. In a. light sectional gun, the combination with the vertical gun pivot, of movably mounted trunnion caps for the gun each provided with a hook-like free end, said pivot being provided with recesses to receive the free ends of said caps, and notched locking bolts for retaining said free ends Within said recesses.

7. In a light sectional gun, the combination with the vertical pivot and the trunnion caps of the gun, of a shield, coacting means on said shield and caps for detachably securing said shield in position, and a retaining ledge on said pivot for engaging the lower edge of said shield.

Dated this 31st day of January 1916,

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
